Requirements: 1. Synthesise the waveforms below. Plot the resulting waveforms and provide the Matlab code used to obtain the plots as well. [1, 1, 1 and 2 marks, respectively] (a) fi(t)=sinwotsin 3wot + sin 5wot - Asin 7wot +.... (b) f2(t) = 0.1(cos wot + cos 2wot + cos 3wat + cos 4wat +...). (c) fa(t)=sinwot-cos 2wat- - 4 15m cos 4wot - 35m 63 cos 6wot-cos 8wot cos 10wot. 99 (d) The waveform in (c) above with the fundamental component (sin wat) switched off. Question: Comment on your results for each waveform. [3, 3, 2 and 2 marks, respectively]
